Induced hypoglycemia. A unusual case of child battering

We describe a case of Munchausen's syndrome by proxy in a 12 years old child. The administration of glibenclamide by the mother led to severe hypoglycemias in the child, who underwent various instrumental researches and a subtotal pancreatectomy before the final diagnosis could be reached. The diagnosis also was possible with the substantial help of an accurate psychological survey. The case solution, with disappearance of hypoglycemias, was made possible by the removal of the maternal presence settled by the juvenile court.     

Reactivation of dormant lumbar methicillin-resistant Staphylococcus aureus osteomyelitis after 12 years.

The adequate treatment of methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis has intrigued clinicians for some time. As the resistance of these pathogens, coupled with the increase in community-acquired cases, continues steadily to rise, clinicians are finding it useful to employ multi-modal approaches for efficacious treatment. The authors present a single case report of a patient with recurrent MRSA osteomyelitis, lumbar paraspinal and epidural abscess. He was found to have decreased muscle strength and was hyporeflexic in the involved extremity. Serum testing demonstrated MRSA bacteremia. Neuroimaging studies revealed evidence of paraspinal abscess and a presumed herniated nucleus pulposus at the L5/S1 interspace with significant nerve root compromise. Despite antimicrobials, his symptoms persisted, necessitating surgical exploration. At surgery, paraspinal and epidural abscesses were encountered and debrided; however, no herniated disc was visualized. This case demonstrates the diagnostic and therapeutic dilemmas with which these lesions present. We postulate that the MRSA osteomyelitis/discitis pathogens were walled off in the disc space and subsequently inoculated the soft tissues with ensuing bacteremia. We concur that antimicrobial treatment should be the first line of therapy for these patients; however, surgical debridements and cautious spinal instrumentation should be employed where appropriate.     

Effect of bezafibrate on low levels of high density lipoprotein cholesterol in normolipidemia. Study in coronary patients and their first degree relatives

A pharmacological study was carried out in a group of 20 subjects composed of 13 coronary patients and 7 normal close relatives (first degree) who were considered at a high risk for coronary heart disease (CHD) because of their low levels of high density lipoprotein cholesterol (HDLch) (mean +/- SD: 34.1 +/- 5.2 mg/dl) and their high total cholesterol/HDLch (Tch/HDLch) ratio (mean +/- SD:6.7 +/- 1.1), despite their normal serum lipid values. With the purpose of normalizing these parameters they were submitted to a 4-month treatment with bezafibrate, a hypolipidemic agent which has a known effect in increasing HDLch and in decreasing the Tch/HDLch ratio. At the end of the study total serum cholesterol and triglycerides decreased significantly by 10 and 30%, respectively (p less than 0.01). HDL increased in its cholesterol content by 33% reaching a value of 45.4 +/- 9.8 mg/dl (mean +/- SD, p less than 0.01) as well as in its apolipoprotein A1 (Apo A1) content (13%, p less than 0.02). HDL2 subfraction also rose in cholesterol and in Apo A1: by 90 and 38%, respectively (p less than 0.01). HDL3 subfraction rised only its cholesterol content by 24% (p less than 0.01). Tch/HDLch ratio was significantly reduced (p less than 0.01) to a value of 4.6 +/- 0.9 (mean +/- SD). Total serum Apo B diminished by 14% (p less than 0.01). No adverse effects were observed during the follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)     

阶段性健康教育对老年食管癌患者术后配合行为的影响

目的探讨阶段性健康教育对老年食管癌患者术后配合行为的影响。方法将51例患者按入院先后分为观察组（26例）和对照组（25例）。观察组实施阶段性健康教育，即住院当日、术前1～3d、术后回病房、术后第1天、拔除胃管当日、出院前1d，由管床护士实施不同内容的健康教育；对照组实施传统健康教育。术后1周评价两组患者术后的配合行为及术后并发症的发生率。结果观察组术后配合行为显著优于对照组（均P〈0．01）；并发症发生率显著低于对照组（P〈0．05）。结论对老年食管癌手术患者实施阶段性健康教育，可提高患者的术后配合行为，降低并发症的发生。     

指背腱膜的解剖学研究

目的 探讨指背腱膜的构成特点及临床意义。方法 在30只成人尸体手标本上，通过模拟手术，对指背腱膜的构成特点进行了应用解剖学观测。结果 指背腱膜的构成复杂，其中的外侧腱束、外侧束、外侧腱和中央束在手指畸形的发生中有着特殊的临床意义。外侧腱束主要形成伸近节指间关节的功能解剖机制；其与外侧束形成的密切纤维联系而具有协同外侧腱的功能；该腱束与屈肌腱鞘有联系又使其具有平衡屈肌和伸肌肌力的作用。中央束在指背腱膜的整体协调、畸形的发生及矫正过程中起着重要的功能。结论 通过对指背腱膜的解剖研究，可以解释因指屈、伸肌腱平衡被破坏后所形成的畸形。     

Use of the Arndt wire-guided endobronchial blocker via nasal for one-lung ventilation in patient with anticipated restricted mouth opening for esophagectomy.

Functional separation of the lungs may be accomplished by several methods. Patient with restricted mouth opening has limited options for one-lung ventilation. We report the use of wire-guided endobronchial blockade, a new tool for achieving one-lung ventilation in a patient with restricted mouth opening requiring nasotracheal, fiberoptic intubation for esophagectomy and reconstruction with gastric tube substitution.

Observations on pathological and histochemical changes in piglet livers infected with Taenia saginata asiatica

To study the pathological and histochemical characteristics of lesions in piglet livers infected with Taenia saginata asiatica (T. saginata asiatica) throughout the different stages, piglets were fed with eggs of T. saginata asiatica and raised in isolation in an animal center to establish the T. saginata asiatica infection model with normal piglets as control. The pathological changes in the piglet livers were observed after the infection using liver sections stained with hematoxylin and eosin. Histochemical methods were used to check the changes in lipid, glycogen and protein content in the liver. The data collected by image analysis were analyzed statistically with Statistical Package for the Social Science. The results show that T. saginata asiatica-exposed piglets were indeed infected. Inflammatory reactions began on the fourth day and progressed rapidly. Kupffer cell hyperplasia, hepatic hydropic degeneration and ballooning degeneration were found in the 10th–20th days after infection. Hepatic central veins and hepatic sinusoids were dilated and congested. Spotty necrosis occurred in some local liver tissues. In the 40th–60th days, granulomatous reactions and mild hepatocirrhosis were the main lesions. In the 70th–80th days, hepatocirrhosis and bile duct proliferation were observed in the liver. In the different stages, lipid drops were increased while glycogen and protein levels were decreased to some degree. There was a significant difference in metabolism between the infected group and the control group (P < 0.01). It is concluded that pigs are the favorable intermediate host of T. saginata asiatica and its infection can result in serious pathological and histochemical lesions in host organs.
